The objective of this study was to evaluate the effect of leisure-time physical activity (LTPA) in the early outcome of coronary artery bypass graft surgery (CABG).
This prospective cohort study analyzed 202 patients submitted to CABG. The patients were assigned to two groups, active or sedentary, according to the practice of LTPA in the preoperative period. The independent variable LTPA practiced by the patients in the previous year of the surgery was evaluated. The occurrence of the major adverse cardiac events as death, acute myocardial infarction, reoperation and the hospital stay after surgery were planned to be evaluated.
The mean age of patients was 62 +/- 10 years, and 134 (66%) were men. Sixty-six (33%) patients practiced LTPA and were classified as active, and 136 (67%) were sedentary. The active group showed 78% less probability (OR= 0.22; CI 95%: 0.09-0.51) to suffer a MACE P<0.001 and a reduction of 33% in length of hospital stay as compared for sedentary patients (HR= 0.67; IC 95%: 0.49 - 0.93). P= 0.018.
LTPA is an important predictor of major adverse cardiac events and hospital stay.
本研究旨在评估休闲体育活动（LTPA）对冠状动脉搭桥手术（CABG）早期预后的影响。
这项前瞻性队列研究分析了202例行CABG手术的患者。根据术前LTPA的情况，将患者分为两组，即活动组或久坐组。评估患者在手术前一年进行的独立变量LTPA。计划评估主要不良心脏事件的发生情况，如死亡、急性心肌梗死、再次手术以及术后住院时间。
患者的平均年龄为62±10岁，其中134例（66%）为男性。66例（33%）患者进行LTPA并被归类为活动组，136例（67%）为久坐组。与久坐患者相比，活动组发生主要不良心脏事件的概率降低了78%（OR=0.22；95%CI：0.09 - 0.51），P<0.001，住院时间缩短了33%（HR=0.67；95%CI：0.49 - 0.93），P = 0.018。
LTPA是主要不良心脏事件和住院时间的重要预测因素。
